Answer:
Nitrates
Explanation:
A. Acid-- acid is right, but not the best answer.
B. Nitrates are fertilizers, which are things that would be used in all of these situations
C. Fuel-- no one is pouring gasoline on their grass to make it grow.
D. Sewage-- same as gas, but this time it is sewage.
Answer:
higher genetic diversity
easily locate a mate
protection from predators
Explanation:
The density of a population is important because whether individuals are crowded or spread out affects their lives and their interactions with each other.
Answer:
B. Nitrogenous bases in each "parent" strand serve as a template for the new strand to be made
Explanation:
DNA replication is the process whereby the contents of DNA is doubled or duplicated. In other words, another copy of DNA is produced from one DNA molecule. The process follows the semi-conservative model, which generally speaks of how one template strand is used to synthesize another new strand.
In the semi-conservative model of DNA replication, the double strand of DNA is unwind and one of the strands called parent strand is used synthesize a complementary strand of DNA. At the end of the process, two DNA molecules results with each having one old strand and one new strand. Nitrogenous bases or nucleotides in each "parent" strand" serve as a template for the new strand to be made.
Impact the amount of carbon in the atmosphere, the biosphere, and the
hydrosphere
Explanation:
The processes of photosynthesis and cellular respiration play a major role in the carbon cycle.
Both these processes are interconnected where the products of a process become reactants of the other process.
Carbon dioxide and water released through cellular respiration become the reactants for photosynthesis which releases oxygen needed for cellular respiration.
The oxygen released is used by animals and human beings for respiration and releases carbon dioxide which is once again used by plants during photosynthesis. This gaseous exchange happening during these two processes helps to maintain atmospheric carbon dioxide levels stable.
In the biosphere, carbon is stored in the organic form in plants and trees. Plants absorb the external atmospheric carbon dioxide and convert it into organic form and store it as food by the process of photosynthesis.
In the hydrosphere, carbon is available as dissolved in water in the water bodies like ocean, rivers, etc. this carbon is absorbed by marine or aquatic plants to undergo photosynthesis and produce their own food. Again the organic carbon is formed and stored in the form of food which is used by other aquatic organisms.
